//! All 8+ benchmark kernels using the ascend-rs tile API.

//! - `ACLRS_CODEGEN_PATH=pto`   → PTO-MLIR → ptoas → AscendC (Huawei Ascend 910B)
//! - `ACLRS_CODEGEN_PATH=nki`   → NKI Python → neuronx-cc (AWS Trainium3)
//! - `ACLRS_CODEGEN_PATH=gpu`   → CUDA kernels (NVIDIA GPU)
//! - `ACLRS_CODEGEN_PATH=musa`  → MUSA kernels (Moore Threads MTT S4000)

//! - `ACLRS_CODEGEN_PATH=aie`   → AIE2P (AMD Ryzen AI)
//! - `ACLRS_CODEGEN_PATH=bang`  → BANG-C (Cambricon MLU370/590)
//! - `ACLRS_CODEGEN_PATH=gaudi` → TPC-C (Intel Gaudi2/3)
//!
//! The tile API is the single Rust source that generates kernels for all targets.
//!
//! All kernels are written against the safe `GmView` API: each `extern "C"`
//! entry point lifts its raw pointer args into shape-annotated views via a
//! `GmDeviceCtx`, then runs in safe code. The op calls go through the
//! `safe::` module which provides no-op safe wrappers around the underlying
//! `#[inline(always)]` intrinsics.
